On simultaneous approximation to a real number and its cube by rational numbers [PDF]
, 2010 One of the fundamental problems in Diophantine approximation is approximation to real numbers by algebraic numbers of bounded degree. In 1969, H. Davenport and W. M. Schmidt developed a new method to approach the problem. This method combines a result on

Do algebraic numbers follow Khinchin's law? [PDF]
, 2021 This paper argues that the distribution of the coefficients of the regular continued fraction should be considered for each algebraic number of degree >2 separately.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

International Journal of Adaptive Control and Signal Processing, EarlyView.This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Approximation to Complex numbers by certain biquadratic numbers [PDF]
, 1975 A result of Davenport and Schmidt related to Wirsing's problem is generalized so that complex numbers are approximated using the algebraic integers T from the field, Q((−D)12), together with numbers of degree two over T.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Measures of algebraic approximation to Markoff extremal numbers [PDF]
Journal of the London Mathematical Society, 2011 Let xi be a real number which is neither rational nor quadratic over Q. Based on work of Davenport and Schmidt, Bugeaud and Laurent have shown that, for any real number theta, there exist a constant c>0 and infinitely many non-zero polynomials P in Z[T] of degree at most 2 such that |theta-P(xi)| < c |P|^{-gamma} where gamma=(1+sqrt{5})/2 denotes
